Error in Property Browser Project

[urmila]

I am using property browser project using variant approach. I have copied a piece of code from the documentation to test it. But it is giving error 4700 uninitialized local variable priority used. My code is:
@void createVariantManagerbrowser(){

QtVariantPropertyManager *variantManager = new QtVariantPropertyManager();
variantManager->addProperty(QVariant::Int, "Priority");
QtVariantProperty *priority ;

priority->setToolTip("Task Priority");
priority->setAttribute("minimum", 1);
priority->setAttribute("maximum", 5);
priority->setValue(3);

QtVariantProperty *reportType = variantManager->addProperty(QtVariantPropertyManager::enumTypeId(), "Report Type");
QStringList types;
types << "Bug" << "Suggestion" << "To Do";
reportType->setAttribute("enumNames", types);
reportType->setValue(1); // current value will be "Suggestion"

QtVariantProperty *task1 = variantManager->addProperty(QtVariantPropertyManager::groupTypeId(), "Task 1");

task1->addSubProperty(priority);
task1->addSubProperty(reportType);

QtTreePropertyBrowser *browser = new QtTreePropertyBrowser();

QtVariantEditorFactory *variantFactory = new QtVariantEditorFactory();
browser->setFactoryForManager(variantManager, variantFactory);
//browser->setFactoryForManager(variantManager, variantFactory);

browser->addProperty(task1);
browser->show();
delete variantManager;
delete variantFactory;
delete browser;

}@
I am unable to understand the problem.
